Vehicle Crash Reconstruction Principles and Technology

Crash reconstruction is a scientific process that utilizes principles of physics and empirical data to analyze the physical, electronic, video, audio, and testimonial evidence from a crash to determine how and why the crash occurred. This course will introduce this reconstruction process as it gets applied to various crash types - in-line and intersection collisions, pedestrian collisions, motorcycle crashes, rollover crashes, and heavy truck crashes. Methods of evidence documentation will be covered. Analysis methods will also be presented for electronic data from event data recorders and for video.

Understanding and Supporting Aircraft Accident Investigation and Reconstruction

Aircraft accident and incident investigations should be supported by all engineering disciplines and departments involved with design, manufacturing, certification, and field operations. For individuals called upon to serve as advisors or technical representatives to official aircraft accident investigation (AAI) teams, an understanding of accident and wreckage reconstruction methodologies and processes is critical to success in this supportive role. This two-day seminar will begin with basic investigative philosophies and procedures.

Side Impact Occupant Safety and CAE

Side impact crashes account for approximately twenty-six percent of all motor vehicle fatal crashes, second only to frontal crashes, according to a report by the National Highway Transportation and Safety Administration (NHTSA). While car companies and suppliers continue to develop new technologies that make vehicles safer, NHTSA rolled out updated safety regulations (FMVSS 214) based on new research studies, making vehicle safety design more and more complex. This seminar is designed to familiarize participants with the engineering principles behind vehicle and restraint designs for occupant safety.

Photography for Accident Reconstruction, Product Liability, and Testing

Many technical projects, most vehicle and component testing, and all accident reconstructions, product failure analyses, and other forensic investigations, require photographic documentation. Roadway evidence disappears, tested or wrecked vehicles are repaired, disassembled, or scrapped, and components can be tested to failure. Photographs are frequently the only evidence that remains of a wreck, or the only records of subjects before or during tests. Making consistently good images during any inspection is a critical part of the evaluation process.

Injuries, Anatomy, Biomechanics & Federal Regulation

Safety continues to be one of the most important factors in motor vehicle design, manufacture and marketing. This seminar provides a comprehensive overview of these critical automotive safety considerations: injury and anatomy; human tolerance and biomechanics; occupant protection; testing; and federal legislation. The knowledge shared at this seminar will enable attendees to be more aware of safety considerations and to better understand and interact with safety experts. This course has been approved by the Accreditation Commission for Traffic Accident Reconstruction (ACTAR) for 18 Continuing Education Units (CEUs).

The Role of the Expert Witness in Product Liability Litigation

Note: Last day of class ends at approximately 1:00 pm According to the Federal Rules of Evidence, an expert witness is anyone who can assist the trier of fact (the jury) in understanding any issue in dispute at trial. The witness' ability to give this assistance can be derived from any specialized training, education, background, or experience. To be effective in providing this assistance, however, requires that the expert witness understand the true role that he or she is to play both before and at the trial.

Tire and Wheel Safety Issues

One of the most important safety critical components on cars, trucks, and aircraft is the pneumatic tire. Vehicle tires primarily control stopping distances on wet and dry roads or runways and strongly influence over-steer/under-steer behavior in handling maneuvers of cars and trucks. The inflated tire-wheel assembly also acts as a pressure vessel that releases a large amount of energy when catastrophically deflated. The tire can also serve as a fulcrum, both directly and indirectly, in contributing to vehicle rollover. This seminar covers these facets of tire safety phenomena.

Photogrammetry and Analysis of Digital Media

2021-09-01
Photographs and video recordings of vehicle crashes and accident sites are more prevalent than ever, with dash mounted cameras, surveillance footage, and personal cell phones now ubiquitous. The information contained in these pictures and video provide critical information to understanding how crashes occurred, and in analyzing physical evidence. This course teaches the theory and techniques for getting the most out of digital media, including correctly processing raw video and photographs, correcting for lens distortion, and using photogrammetric techniques to convert the information in digital media to usable scaled three-dimensional data.

Reconstruction and Analysis of Rollover Crashes of Light Vehicles

2020-11-02
For automotive engineers involved in crash reconstruction and analysis, a knowledge of basic accident reconstruction principles and techniques is essential, but often insufficient to answer all of the questions posed by design engineers, regulators, and lawyers. This seminar takes participants beyond the basics of accident reconstruction to physical models and analysis techniques that are unique to the reconstruction of single-vehicle rollover crashes.

Advanced Applications of Heavy Vehicle EDR Data

2020-10-26
This class will provide the student with the skills, knowledge, and abilities to interpret, analyze and apply Heavy Vehicle Event Data Recorder (HVEDR) data in real world applications. This course has been designed to build on the concepts presented in the SAE course Accessing and Interpreting Heavy Vehicle Event Data Recorders (ID# C1022).

Reconstruction and Analysis of Motorcycle Crashes

2020-10-16
The reconstruction and analysis of motorcycle crashes requires a specialized set of skills and knowledge beyond those required for typical four wheel vehicles. This seminar takes participants beyond the basics of crash reconstruction to physical models and analysis techniques that are unique to the reconstruction of motorcycle crashes, providing learners with a comprehensive summary of applicable reconstruction techniques.

Accident Reconstruction, the Autonomous Vehicle and ADAS

2020-10-05
After the crash, you need to know if an autonomous or driver assistance system was installed in the vehicle, if it functioned properly, and if it affected the outcome of the accident. Get a detailed look at the rapidly growing field of self-driving vehicles and driver assistance systems. What is available, how does it work, and what will happen in a crash scenario? How does it affect product liability and accident reconstruction? Some auto manufacturers are equipping the majority of their new vehicles with such technology, and it’s important for the forensic engineer to “stay ahead of the curve”.

Applying Automotive EDR Data to Traffic Crash Reconstruction

2020-09-14
EDR's were first installed in 1994 and are now installed in 99% of new light vehicles sold in the US. In the US EDR’s are not required, but vehicles with EDR’s made after 9/1/2012 must meet minimum standardized content requirements of 49 CFR, Part 563 including speed, throttle, brake on/off and Delta V. Data must be retrievable with a publicly available tool. Only a few manufacturers install EDR’s worldwide currently, but the EU and China are adopting regulations to require them in the next few years.

WIP
J3166
The document will define and describe in condensed form the fundamental theoretical concepts of surrogate measures of safety and define indicators (with variations). To the extent possible, the definitions should be kept neutral with respect to the technology or data collection method used as these change rapidly.

Comparing Dolly Rollover Testing to Steer-Induced Rollover Events for an Enhanced Understanding of Off-Road Rollover Dynamics

2011-11-01
The field of motor vehicle rollover research and testing has been one of multiple and varied approaches, dating back to at least the 1930's. The approach has been as simple as tipping a vehicle over at the top of a steep hill ( Wilson et al., 1972 ), to as complex as releasing a vehicle from an elevated roll spit mounted to the rear of a moving tractor and trailer ( Cooper et al., 2001 and Carter et al., 2002 ).
